Drill down doesn't work when exporting to Excel (RS2000)

I've created a drill down rpt in RS2000, but when I setup subscription and receive it as Excel, the file doesn't contain any drill downs.
Does anyone have any idea the reason for this??
thx,
John

I figured it out, it seems to be a RS2000 bug. When setting up your groups and visibility, set up the visibility/toggle from the properties box for that group row.
